.SPECIFICATION forming part of Letters Patent No. 723,984, dated March 31, 1903. Application led December 12, 1902,' Serial No. 13A-2,890. (No model.)

To a/ZZ wtorrt t may concern: f

a citizen of the United States, residing in the city and county ofv San Francisco, State of facility and adapted not only to support thestovepipe, but also to limit the insertion of said pipe into the chimneyue, so that it will Vnot abut against the inner ue-wall,and thereby interrupt the draft and passage of the' smoke, and adapted also to lock itself in the fiue so that it will neither move in nor out, thereby completely fastening the s-tovepipe.

My invention consists in the novel constructions and combinations of parts constituting the stovepipe-fastener and which I shall now fully describe and claim by reference to the accompanying drawings, in which- Figure l is a perspective view of the fas-I tener, showing the locking-strap in the plane of the stop-strap, both parts being in posi-V tion to be compressed laterally to enter the stovepipe-hole. Fig. 2 is a perspective view of the fastener, showing the locking-strap y turned at right angles to the stop-strap to its locking position. Fig. 3 isa vertical section of a chimney, showing the application of the fastener to the stovepipe and the chimney. Fig. 4 is a cross-section of same.

A is a .strap formed of metal sufciently thin to be compressible or elastic. This strap has a bow end ct and extended arms d and may be termed the stop-strap.`

B is a strap of similar elastic or compressible material. It is annular or ring-shaped in contour, having a little lessradius than the radius of the bow (t of strap A. This strap may be termed the locking-strap. Strap B is pivoted at b within strap A and is adapted to be turned on its pivots to lie in the i `plane of strap A, as shown in'Fig. l, or tolie Be it known that I, FREDERICK H. BUSBY,

in a plane at right angles thereto, as shown in Fig. 2. Y

' C, Figs. 3 and 4,'is Aa chimney of any kind, having a flue c and a stovepipe-hole c. In the Vnorm ally expanded condition ofthe straps A and B they will not passinto the stovepipehole c', and to secure ,this result they are purposelyvmade Wider than the diameter of the hole; but ifwhen the annular locking-strap B islying within and in the plane of stop-strap A,

-as in Fig. 1, they be compressed from each side they will elongate suiiicien tl y to allow them to pass into the stovepipe-hole. When they have entered sufficiently transversely of the 'chimhey-flue c to let the forward arc of the locking- ,strap B clear the front wal-l'l of the iue,said

locking-strap is then by the inserted hand turned on its pivotsb to aplane at right ang-les to strap A, as in Fig. 2, in which position it liesin the plane of the lengthof the line, Fig. 3, and directly behind or within thel front Wall of said iue. Having been relieved of itsentering compression, the locking-strap B expands to its full diameter, and its shape is then such that it is too large to bewithdrawn from the stovepipe-holajFig. 3, and -the device is thereby securely held in the chimney, with the bow end a of stop-strap A near or in contact with the back wall of the Hue, Figs. 3 and 4, the arms et projecting forwardlyout of the stovepipe-hole and the locking-strap B disposed up and down'ibehind the inner rim of said hole and too large to come out.

The stovepipe D is fitted through hole aand its end is limited in its inward projection by contact with the bow end a of stop-strap A .far enough from the hack wall of the flue to permit free draft and passage of the smoke. Outsidethe holethe stovepipe may be secured to the arms ct of strap A in any suitable manner.. I havel here shown a couple of nails d for this purpose,` Fig. et.

If desired, though-it is not essential, small angle-brackets cma'y be secured to the outer surfaces of the arms a', which said brackets may be-secured to the face of the chimney; but it is obvious that without these brackets the device is securely held in place, for it cannot be pushed in farther than the contact of the bow end a, with the inner or back wall of the tine, nor can it be pulled out farther than IOO bers of these devices for transportation, I

deem it best to sever the locking-strap B at about the middle of its front are, as seen in Fig. l, making the severed ends overlap, whereby they may, when the device is about to be used, be riveted by a rivet b'. When being packed,both straps may be straightened out, lying on one another, and thus presenting straight strips adapted to be secured in bundles with advantage as to space. l/Vhen a fastener is be used, the stop-strap A is bent to its bowed form and the locking-strap B is curved to its annular form and its severed overlapping ends united by rivet 1)'.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A stovepipe-fastener comprising a laterally-compressible member to which the stovepipe is to be secured, and a second compressible member pivoted to the first member and adapted to be turned to the plane of saidl member and to a plane at an angle thereto, both members being normally too wide to enter the stovepipe-hole, but laterally compressible therethrough when they lie in the same plane, whereby when entered into the chimney-flue the second member when turned to an angle with the rst member engages behind the front wall of the flue.

2. A stovepipe-fastener comprising a laterally-compressible member to the outer end of which the stovepipe is to be secured, the inner end of said member forming a stop, and a second compressible member pivoted to the `first member and adapted to be turned to the plane of said member and to a plane at an angle thereto, both members being normally too wide to enter the stovepipe-hole, but laterally compressible therethrough when they lie in the same plane, whereby when entered into the chimney-flue the inner stop end of the Irst member limits its insertion, and the second member when turned to an angle with the first member engages behind the front wall of the flue.

3. A stovepipe-fastener comprisinga laterally-compressible stop member formed with a bowed end and extending arms, the latter to receive and secure the stovepipe, and an annular compressible locking memberpivoted Within the stop member and adapted to be turned to the plane of said stop member and to a plane at an angle thereto, both members being normally too wide to enter the stovepipe-hole, but laterally compressible therethrough when they lie in the same plane, whereby when entered into the chimney-flue, the bow end of the stop member forms a stop for the fastener and for the stovepipe, and the annular locking member when turned to a plane at an angle to the stop member engages behind the front wall of theflue and locks the fastener against withdrawal.

4. A stovepipe-fastener comprising the laterally-compressible bowed strap with its arms for receiving and securing the stovepipe, and the annular compressible strap pivoted at its sides in the bowed strap, and adapted to be turned to and from the plane of the bowed strap.

5. A stovepipe-fastener comprising the laterally-compressible bowed strap with its arms for receiving and securing the stoveppe, and the annular compressible strap pivoted at its sides in the bowed strap and adapted to be turned to and from the plane of the bowed strap, said annular strap being jointed in its forward are.

In Witness whereof I have hereunto set my hand.
